The Ruetz [ruət͡s] is an approximately 35 km long left tributary of the Sill in Tyrol , which drains the Stubai Valley .
course
The Ruetz arises near the main Alpine ridge from the confluence of Fernaubach and Mutterbergbach at the Mutterbergalm, directly at the valley station of the Stubai Glacier ski area . The source streams are fed by the glaciers on the main ridge of the Stubai Alps . The Ruetz flows in a north-easterly direction through the Unterbergtal, the uppermost section of the Stubai Valley, takes in the Oberbergbach from the left between Milders and Neustift and the Pinnisbach from the right at Neder . It then passes Fulpmes , where the Schlickerbach joins from the left. Below Fulpmes, the Ruetz has cut deeply into the old valley floor on which Telfes and Mieders are located. At Schönberg in the Stubai Valley , it turns north and flows in a narrow gorge parallel to the Sill. After the Ruetz has passed under the Stephansbrücke , shortly afterwards it flows into the Sill in the Wipptal . The municipal areas of Schönberg, Mutters and Innsbruck meet at the mouth .
The Ruetz measures 34.7 km to the confluence of the Fernaubach and Mutterbergbach rivers; with the Daunkogelfernerbach as the longest source brook, it is 38.8 km long and has an altitude difference of around 2000 m.
Catchment area and water supply
The Ruetz has a natural catchment area of 321 km², of which (as of 2007) 24.6 km² (7.7%) are glaciated. The drainage of the Alpeiner Bach, the upper reaches of the Oberbergbach, into the Längental reservoir of the Sellrain-Silz power plant group has reduced the effective catchment area by 23.7 km². The highest point in the catchment area is the Zuckerhütl at 3507 m above sea level. A.
The mean discharge at the Krößbach gauge, 20 km above the estuary, is 5.31 m³ / s, which corresponds to a discharge rate of 41.6 l / s · km². The Ruetz has a nivo-glacial discharge regime with a strong amplitude, which is significantly influenced by the snow and glacier ice melt. The runoff is lowest in the winter months, in spring it increases significantly and reaches its peak in summer, before rapidly declining again in autumn. The monthly mean of the month with the highest discharge, July, is 14.2 m³ / s, more than 24 times as high as that of the month with the lowest discharge, February, with 0.58 m³ / s. The mean discharge in Fulpmes, 8.2 km above the mouth, is 9.52 m³ / s, with a discharge of 33.8 l / s · km².
The Ruetz was a feared white water river until it was built up and caused devastating damage several times, especially in the municipality of Neustift in the Stubaital, the last time in 1987. The effects of the Sill were occasionally felt as far as the Inn Valley.
Economic use
From 1912 to 1983 the water of the Ruetz was conducted from Fulpmes via an aqueduct to Schönberg and from there through a pressure pipe to the Ruetz power station to generate traction current. A shaft power plant in Fulpmes has been generating electricity for the ÖBB since 1983 , among other things to supply energy to the Brenner Railway .
environment
The banks are built continuously from Ranalt to Fulpmes, in this area the river bed is also partially paved. In the upper reaches and in the gorge stretch from Mieders to the mouth, the river is somewhat more natural. The Ruetz has water quality classes I-II throughout its course .
Surname
The Ruetz is first mentioned around 1250 as Rutzein , 1383 as daz wazzer in Stubay the Ruseinbach . In Emperor Maximilian's hunting book it is called Ruetz , but in his fishing book it is named after the valley of the Stubacher Bach . There are several interpretations of the name. a. with grödnerisch Roia ( "torrent") and welschtirolerisch Roza ( "channel") associated or ruezzan derived ( "dig").
Others
A march, the Ruetz March by Erwin Trojans , was also dedicated to the Ruetz .
